SPECIFICATION forming part of Letters Patent No. 278,262, dated May 22, 1883. Application iiled December 2, 1881. Rencwe d September 28. 1882. (No model.)

To all whom. it may concern:

Be it known thatI, OHRIsTOPHER H. OLsoN, a resident of the city of Decatur, county of Macon, and State of Illinois, have invented a certain new and useful Device for Adjusting Joint-Fasteners, of which the following is a specification, and which has never been patented tome nor to others with my knowledge and consent in any foreign country.

My invention consists in a pair of pinchers the joint-fastener, and the lowerjaw provided with an offset for the proper adjustment of said joint-fastener.

In the drawings accompanying and forming a part of this specification, Figure 1 represents my device as operated, and Fig. 2 shows a A is the pinchers, provided with jaws a b, bent as shown. B is thejoint-fastener, held in position to be driven into piece 0, which forms a joint with Oin Fig. 2.

In making a joint it is necessary togive the screw room to draw, and to accomplish this I construct the ott'set c in ja'w b, which permits 2 the fastener to set in, as shown in Fig. 2. v

In Fig. 2 the jointis not represented as complete, as the screw, when tightened, draws the fastener firmly against piece 0.

In operation the joint-fastener is placed in 0 the jaws, as shown, and the lower jaw used I as a gage to determine the proper position of the points of the fastener, thereby making it possible to attach the same speedily and with accuracy. 3 5

Iclaim- The pinchers A, provided with jaws a b, of unequal length, bent at an angle to the handles, and the longerjaw having an ofl'set, as shown, and for the purpose set forth.
